Abstract

The present invention generally relates to assistive hearing devices. In one aspect, an apparatus for use in amplifying certain frequencies and canceling other frequencies is provided. The apparatus is insertable at least partially through a tympanic membrane of a user. The apparatus includes an actuator for stimulating an eardrum. The apparatus further includes an acoustic sensor for measuring a level of acoustic energy transmitted to an ear canal and/or the ear drum of the user. Additionally, the apparatus includes an electronics package for controlling the actuator and the acoustic sensor, wherein the electronics package is configured to transmit amplified selected sound waves while canceling out other sound waves having a particular frequency or frequencies. In another aspect, an apparatus for use in measuring a parameter in a body is provided. In a further aspect, a method of selectively transmitting sound waves having a predetermined frequency or frequencies is provided.

Claims

1. An apparatus for use in amplifying certain frequencies and canceling other frequencies, which apparatus is insertable at least partially through a tympanic membrane of a user, the apparatus comprising:

an actuator for stimulating an eardrum;

an acoustic sensor for measuring a level of acoustic energy transmitted to an ear canal and/or the ear drum of the user; and

an electronics package for controlling the actuator and the acoustic sensor, the electronics package configured to transmit amplified selected sound waves while canceling out other sound waves having a particular frequency or frequencies.

2. The apparatus of claim 1, further comprising a receiver electrically coupled to the electronics package.

3. The apparatus of claim 2, wherein the receiver comprises a frequency modulated receiver.

4. The apparatus of claim 2, wherein the receiver is configured to be tunable from a remote location.

5. The apparatus of claim 4, wherein the receiver is configured to receive and transmit information regarding alterations in specific auditory frequency settings.

6. The apparatus of claim 1, further comprising a member for retaining the apparatus in the tympanic membrane.

7. The apparatus of claim 1, further comprising a plurality of actuators coupled to the electronics package.

8. The apparatus of claim 7, wherein at least one of the actuators is adapted to be external to the tympanic membrane and/or at least one of the actuators is adapted to be internal to the tympanic membrane.

9. The apparatus of claim 1, further comprising a housing with a component configured to dampen vibrational movement and limit a Doppler Effect.

10. The apparatus of claim 1, wherein the electronics package is configured to receive, amplify, and transmit signals or sound waves that are not audible to a person.

11. The apparatus of claim 1, wherein the apparatus is configured for use in covert communication.

12. The apparatus of claim 1, wherein the apparatus is configured for use in noise cancellation of a frequency or combination of frequencies.

13. The apparatus of claim 1, wherein the electronics package is configured to dampen vibrational movement and limit a Doppler Effect.

14. An apparatus for use in measuring a parameter in a body, which apparatus is insertable at least partially through a tympanic membrane of a user, the apparatus comprising:

a member for stimulating an eardrum;

a sensor for measuring an acoustic or mechanical energy from the tympanic membrane;

and an electronics package for controlling the member and the sensor, the electronics package configured to measure a temperature, a heart rate, a blood pressure, a respiratory rate, oxygenation, other physiologic parameters or combinations thereof.

15. A method of selectively transmitting sound waves having a predetermined frequency or frequencies, the method comprising:

inserting an apparatus at least partially through a tympanic membrane of a user, the apparatus comprising an actuator, an acoustic sensor and an electronics package;

receiving sound waves in an ear canal of the user;

filtering out the sound waves having the predetermined frequency or frequencies from other sound waves by utilizing the electronics package; and

transmitting the sound waves having the predetermined frequency or frequencies to the tympanic membrane of the user by utilizing the actuator.

16. The method of claim 15, further comprising detecting acoustic and mechanical energy from the tympanic membrane.

17. The method of claim 16, wherein selectively enhanced frequencies are transmitted via the actuator back to the tympanic membrane in phase or out of phase of the acoustic and mechanical energy.

18. The method of claim 15, wherein covert communications are detected, decoded, and transmitted via the actuator to the user.

19. The method of claim 18, wherein the transmitted signal is directed to the tympanic membrane.

20. The method of claim 15, further comprising modifying the predetermined frequency or frequencies by amplifying selected frequencies or canceling other frequencies.
